Today's APOD is a very beautiful portrait of AE Aurigae and the complex patterns of surrounding dust, gas and reflection nebulosity.
I need some help here, though. Adam Block's image shows two stars surrounded by reflection nebulosity, blue AB Aur and yellowish - yes, what's the name or designation of the yellowish star? My software doesn't show it. The star's surrounding reflection nebula is yellow, which is unusual. And there is what looks like a jet shooting out from the star, between two diffraction spikes.
By the way, is north up and east to the left in this image?
I have another question. How long does it usually take for planetary bodies to coalesce out of the protoplanetary disk of a young star?
